The term “Opacity Chart”, as used in this catalog, refers to charts on which the test pattern is a simple combination of black and white areas, large enough for wide aperture reflectance instruments, as well as for visual opacity and color observations. Leneta opacity charts comply with all test methods specifying charts of such ... more

Penopac Charts
These combine the test areas and functions of a penetration and an opacity chart. They can be considered as universal test charts for research, development and quality control. The choices offered in size and design are responsive to individual laboratory needs and preferences. Form 19BR includes an unlacquered black area, but ... more

These charts employ time-tested diagonally striped patterns, having a strong visual impact that emphasizes variations in film opacity. They are therefore frequently used for hiding power display purposes, by means of drawdowns or brushouts. Gray stripes in Forms 8H-GW and 8K-GW provide reduced substrate contrast for use with low hiding power ... more

Charts of this type combine the large, unbroken areas that are characteristic of Opacity Charts, with the striped design of a Display Chart. The larger areas permit wide aperture photometric measurements and visual color comparisons, while the striped area is uniquely effective for hiding power comparison and display. Spreading Rate Charts ... more

One of the earliest hiding power test surfaces was linoleum with a black and white checkerboard pattern. This was soon replaced by sealed paperboard charts of which Forms 10H and 10H-BG Spreading Rate Charts are typical examples. Designed for brushout tests at specified spreading rates such as in ASTM Method D 344 and Canadian 1-GP-71, they ... more

Duplex Applicator Charts
Originally made to be used with the “Duplex Applicator”, an instrument designed for rapid production of side-by-side drawdowns, they now serve mostly as generic paint test charts.

Brushout Cards Nominal Thickness: 20 mils (0.5 mm)
Designed for informal brushout applica-tions, the paper stock is almost twice the thickness of regular chart paper to give greater rigidity for more convenient handling. They are also used widely for drawdowns and colorimetric measure-ments.
